2 Claims.

This invention relates to a device which is adapted to be attached to astandard cop. so that said cop normally used in non-automatic plainlooms may, with the device of this invention at- 5, tached thereto, beused as a quill on shuttlechanging automatic looms.

An object of the invention is the construction of a novel device adaptedto be attached to cops so that the use of said cops may be extended, i.e.

they may be used in a larger variety of looms. Other objects of theinvention will appear from .the following detailed description anddrawing. The shuttle and shuttle-changing device of an automatic shuttlechanging loom requires the yarn to be wound upon a special quill havinga heavy head circled with ridges that are adapted to be gripped byholders in the shuttle, while many non-automatic looms require the yarnto be wound upon a cop that merely a flange for a head. The quills areusually made of wood coated with lacquer or enamel and have heavy wirerings circling the while the cops are usually made of vulcanized fiber,pressed paper, cardboard, etc., with a thin metal sleeve having a flangepressed over the fiber core to form the head. This invention isconcerned with a device adapted tobe attached to a core to make it ineffect a quill, thus permittinthe yarn manufacturer to wind the yarnonly on one size cop for both classes of looms. By winding of yarn onlyon cops not only is the amount of reserve stock required by themanufacturer kept to a but also a lesser number of winding machines isrequired on which winding spindles are of only one size. Moreover, byemploying in either type of loom a cheaper package core as well asreducing the number of reserve cops, the cost of the said yarn holdersis reduced.

In accordance with our invention, we construct a device for attachmentto a cop filled with yarn, thus producing a package of yarn that may besubstituted for quills in any fabric-forming de vices where such yarnpackages are normally required. This weaving'deviceor cop attachment isformed with a head having ridges or rings such that it readily intosuitable gripping devices onshutties requiring the heavy head found onquills.

In the drawing, wherein any like reference numorals refer to the same orsimilar elements in the respective vie there is shown a weaving device,or cop attachment, constructed in accordance with our invention. In thedrawing:

Fig. l a view partially in section of a cop in operative position withour weaving device,

Fig. 2 is a plan view taken on line 2-2 in Fig. 1 and on a slightlylarger scale, of the weaving device with the cop removed,

Fig. 3 is an end view taken on the line 3-3 of Fig. 2, and 5v t is anelevational view of the head of the weaving device.

The cops normally employed in non-automatic shuttle-changing loomsconsist of a core I made of pressed fiber or other similar material andhas 1 a short metallic sleeve 2 pressed over one end of same. The sleeve2 is formed with a yarn-retaining flange 3 and slippage-preventinggrooves 4. The metallic sleeve 2 pressed on to the core I is held inplace in any suitable manner, such as by 15 punching the walls of thesleeve into the core proper or by the use of lacquers, cements or both.Another type of metallic sleeve 2 may be employed for use with loomshaving an electric ieeler. This type is illustrated but differs onlyfrom the above 20 in that the length of the metallic sleeve is longer.

The weaving device, or cop attachment, comprises a cop-supporting member5 which is in the form of a rod having a diameter slightly less than theinside diameter of the cop and may be made 25 of wood, metal, vulcanizedfibre, synthetic plastics or other suitable material. The supportingmember is provided with a collar 6 against which the flange 3 of the copis adapted to abut. The supporting member 5 is also provided with a 30spring formed of any suitable resilient metal such as copper, steel andthe like. This spring is preferably in the form of a disc 8 having ahole therein through which the supporting member 5 may be inserted andtwo or more fingers 1 and 9, 35 so shaped to extend over the collar 6and engage the flange on the cop. Two fingers l as shown in the drawingor three fingers spaced apart may be employed.

The spring is held between the collar 6 and a, 40 head H. The head i Imay be formed of any suitable material such as an aluminum alloy, wood,artificial resins or the like. Surrounding the head II is a metallicsleeve i2 having ridges or rings l3v thereon, adapted for gripping the45 shuttle of an automatic quill changing loom, positioned in a mannersimilar to the wire rings on a quill. The ridges l3 may be formedintegral with the sleeve l2 or they may be formed of wire rings normallyplaced upon the wooden quills by 50 forming grooves in the sleeve l2 andplacing thereon wire rings. The head i i is held in place upon thecop-supporting member by means of a rivet pin 14. The head I l isslotted as at I5 allowing for free lateral movement of the spring 55fingers I and 9. In place of the open slot I5, as shown on the drawing,only the small portion of the sleeve 12 may be cut out leaving at leasta part of the rings I3 covering the groove thus formed.

In operation, yarn is Wound upon cops and when it is desired to usethese cops in an auto matic quill-changing loom which requires the yarnto be on quill, the cop-supporting member or weaving device is insertedinto the cop until the flange 3 thereof abuts against the collar 6 ofthe Weaving device. When the cop is in this position, the spring fingersI and 9 press into the flange on the base of the cop, thus steadying thecop from wobbling or inclining towards the bottom of the shuttle. Thespring fingers also prevent the cop from sliding off the cop-supportingmember 5. Each quill-changing automatic loom may be provided withseveral of these weaving devices or attachments and the operator insertssame in cops and places them in the magazines, or each shuttle may beprovided with one of these attachments. Alternatively, when yarn is tobe used upon automatic shuttle-changing looms, the manufacturer mayattach the weaving device to all the cops to be employed in these looms.

Other modification of the device may be employed. For instance, ashorter assembly may be produced by omitting the collar 6 andcounterboring to offset the difference. In addition, other types ofspring means than are shown in the drawing as springs 1 may be employed.Thus, a circular groove may be formed in the inside of sleeve l2 to takea hexagonal piano spring wire or the like. In this modification, as theflange of the cop contacts the spring it contracts, allowing the base ofthe cop to fit snugly against the collar 6, or the head H if no collaris employed, and then expands, gripping the forward and top edge of theflange 3.

It is to be understood that the foregoing detailed description anddrawing is given merely by Way of illustration and that many variationsmay be made therein without departing from the spirit of our invention.

Having described our invention, what we desire to secure by LettersPatent is:

1. A weaving device for adapting the cop type of yarn package to loomsnormally employing a quill, said device comprising a cop supportingmember, said cop supporting member having a recess adapted to receivethe flange of a cop tube, a collar in said recess adapted to abutagainst said flange, said collar being of smaller diameter than saidflange and spring means clamped between said collar and said copsupporting member adapted to engage with said flange and to retain it inabutment against said collar.

2. A Weaving device for adapting the cop type of yarn package. to loomsnormally employing a quill, said device comprising a cop supportingmember, said cop supporting member having a recess adapted to receivethe flange of a cop tube, a collar within said recess adapted to abutagainst said flange, said collar being of smaller diameter than saidflange and spring means comprising a plurality of spring fingers clampedat their bases between said collar and said supporting member, saidspring fingers being adapted to engage with said flange and retain it inabutment against said collar.
